Radioulnar Contrasts in Fingerprint Ridge Counts: Searching for Dermatoglyphic Markers of Early Sex Development
Original language description
Objectives Using prenatally fixed dermatoglyphics features as markers of prenatal sex development is limited due to insufficient knowledge on their sex differences. This study aims to examine more thoroughly sex differences in radioulnar contrasts. Methods Fingerprints of 360 females and 331 males from 4 samples of different ethnic backgrounds (Czechs, Slovaks, Vietnamese and Lusatian Sorbs) were studied. On both hands, finger ridge-counts were recorded, and all possible radioulnar contrasts were computed as a difference between ridge-count at a radial position minus ridge-count at a respective ulnar position on the hand. Radioulnar contrasts with population-congruent and numerically large dimorphism were selected and the dimorphism of the selected radioulnar contrasts was then tested using nonparametric analysis of variance. Results Greater dimorphism of radioulnar contrasts occurred on the right hand than on the left hand. Population congruent direction and relatively strong dimorphism (Cohen's d greater than 0.3) was found in six radioulnar contrasts on the right hand, all of which involved the radial ridge-count of the 2nd finger. Of these, the highest average dimorphism was observed for the difference between the radial ridge-count of the 2nd finger and the ulnar ridge-count of the 4th finger (2r4u contrast), where the average effect size from all 4 population samples was comparable to a published average effect size of the 2D4D finger length ratio. Conclusion We propose that 2r4u contrast of ridge-counts could serve as a marker of prenatal sexual development targeting a temporally narrow developmental window.
